The Role Of Adherence In Mediating The Relationship Between Depression And Health Outcomes, Rena R. Wing, Suzanne Phelan, Deborah Tate

Kinesiology and Public Health

Depression has been linked to poor health outcome in a number of studies; however, the mechanism underlying this relationship has received little attention. This paper explores the possibility that adherence mediates the relationship between depression and outcome. Principal findings regarding the relationship between depression, adherence, and outcome are reviewed. The data suggest that depression is related, at least moderately, to poorer adherence to a variety of treatment components. The relationship between adherence and outcome is more difficult to establish. In addition, current data, albeit limited, do not support the hypothesis that adherence mediates the relationship between depression and outcome. An …

Progressive overload through the range of motion (ROM) is important for proper rehabilitation of muscle strength, yet varies across types of resistance for a given exercise. The purpose of this study was to compare strength curves (SC) for shoulder internal (IR) and external rotation (ER) with resistance curves (RC) for two application angles (A and B) of Thera-Band® resistance to determine which application angle best overloads IR and ER through the ROM. Thirty volunteer subjects participated in this study. SCs were obtained experimentally by measuring maximal isometric torque for IR and ER from 30° to 135°. RCs were calculated using …

Effects Of Two Backpack Weight Distributions On Perceptual And Physiological Measures During Walking, Katelyn Wells-Fahling

Masters Theses & Specialist Projects

Backpack weight distribution may affect economy by conserving energy and thus potentially prolonging fatigue. Research has not however examined effects of backpack weight distribution on subjective measures of intensity and comfort. Heart rate (HR) and overall and differentiated Ratings of Perceived Exertion (RPE) were examined during simulated backpacking with differentially weighted backpacks. Volunteers (n=27) completed two simulated hiking trials on a treadmill. Trials consisted of 15 minutes walking at 0% grade followed by 15 minutes walking at 10% grade at 2.5 mph (males) or 2.0 mph (females). Subjects wore an internal frame backpack packed to contain 25% of their individual …

Dietary Patterns And Prostate Cancer Risk In The Nhefs Cohort, Marilyn Tseng

Kinesiology and Public Health

We examined the association between dietary patterns and prostate cancer risk using data from the first National Health and Nutrition Examination Epidemiologic Follow-up Study. The study population included 3,779 men followed 1982-4 to 1992, with 136 prostate cancer cases identified during the follow-up. Principal components analysis on responses to a lOS-item diet questionnaire in 1982-84 was used to identify dietary patterns, and scores representing level of intake of each pattern were categorized into tertiles. Three distinct patterns were identified: a vegetable-fruit pattern, a red meat-starch pattern characterized by intake of beef, pork, potatoes, and sweets, and a southern pattern characterized …

Combining Behavioral And Pharmacological Treatments For Obesity, Suzanne Phelan, Thomas A. Wadden

Kinesiology and Public Health

Weight-loss medications are currently recommended for use only as an adjunct to diet, exercise, and behavior modification. Little, however, is known about the benefits of combining behavioral and pharmacological therapies or about the mechanisms that would make these combined approaches more effective than either used alone. This article reviews the effects of adding pharmacotherapy (i.e., principally sibutramine and orlistat) to a modest program of lifestyle modification. Studies revealed that the addition of medication typically improved short- and long-term weight loss compared with lifestyle modification alone. The best results, however, were obtained when medications were combined with an intensive, group program …

We Want To Play Too, Peter J. Titlebaum, Kate Brennan, Tracy Chynoweth

Health and Sport Science Faculty Publications

The Americans with Disabilities Act (ADA) requires that persons with disabilities be integrated to the maximum extent possible, and that these persons cannot be excluded from participation. Intramural directors need to be proactive in this area. The benefits of intramural sports are vast, and they help many students become part of the college community.

Forming an alliance with the Disability Services on campus, the first step, is the most vital aspect of making these programs successful. It is important to remember the difference between what can be done and what must be done. Even with the best of intentions, it …

Effect Of Normalization And Phase Angle Calculations On Continuous Relative Phase, Max J. Kurza, Nikolaos Stergiou

Journal Articles

The purpose of this investigation was to determine if phase plot normalization and phase angle definitions would have an affect on continuous relative phase calculations. A subject ran on a treadmill while sagittal plane kinematic data were collected with a high­ speed (180Hz) camera. Segmental angular displacements and velocities were used to create phase plots, and examine the coordination between the leg and thigh. Continuous relative phase was calculated with a combination of two different amplitude normalization techniques, and two different phase angle definitions. Differences between the techniques were noted with a root mean square (RMS) calculation. RMS values indicated …

A Motor And A Brake: Two Leg Extensor Muscles Acting At The Same Joint Manage Energy Differently In A Running Insect, Anna N. Ahn, Robert J. Full

All HMC Faculty Publications and Research

The individual muscles of a multiple muscle group at a given joint are often assumed to function synergistically to share the load during locomotion. We examined two leg extensors of a running cockroach to test the hypothesis that leg muscles within an anatomical muscle group necessarily manage (i.e. produce, store, transmit or absorb) energy similarly during running. Using electromyographic and video motion-analysis techniques, we determined that muscles 177c and 179 are both active during the first half of the stance period during muscle shortening. Using the in vivo strain and stimulation patterns determined during running, we measured muscle power output. …

Exercise and Sport Studies: Faculty Publications

We measured blood erythropoietin (EPO) concentration, arterial O2 saturation (SaO2), and urine PO2 in 48 subjects (32 men and 16 women) at sea level and after 6 and 24 h at simulated altitudes of 1,780, 2,085, 2,454, and 2,800 m. Renal blood flow (Doppler) and Hb were determined at sea level and after 6 h at each altitude (n = 24) to calculate renal O2 delivery. EPO increased significantly after 6 h at all altitudes and continued to increase after 24 h at 2,454 and 2,800 m, although not at 1,780 or 2,085 m. The increase in EPO varied markedly …

Foot Strike Patterns After Obstacle Clearance During Running, Shane D. Scholten, Nicholas Stergiou, Alan Hreljac, Jeremy J. Houser, Daniel Blanke, L. Russell Alberts

Journal Articles

Purpose

Running over obstacles of sufficient height requires heel strike (HS) runners to make a transition in landing strategy to a forefoot (FF) strike, resulting in similar ground reaction force patterns to those observed while landing from a jump. Identification of the biomechanical variables that distinguish between the landing strategies may offer some insight into the reasons that the transition occurs. The purpose of this study was to investigate the difference in foot strike patterns and kinetic parameters of heel strike runners between level running and running over obstacles of various heights.

Methods

Ten heel strike subjects ran at their …

Skin Cooling Maintains Cerebral Blood Ffow Velocity And Orthostatic Tolerance During Tilting In Heated Humans, Thad E. Wilson, Jian Cui, Rong Zhang, Sarah Witkowski, Craig G. Crandall

Exercise and Sport Studies: Faculty Publications

Orthostatic tolerance is reduced in the heat-stressed human. The purpose of this project was to identify whether skin-surface cooling improves orthostatic tolerance. Nine subjects were exposed to 10 min of 60° head-up tilting in each of four conditions: normothermia (NT-tilt), heat stress (HT-tilt), normothermia plus skin-surface cooling 1 min before and throughout tilting (NT-tiltcool), and heat stress plus skin-surface cooling 1 min before and throughout tilting (HT-tiltcool). Heating and cooling were accomplished by perfusing 46 and 15°C water, respectively, though a tube-lined suit worn by each subject. During HT-tilt, four of nine subjects developed presyncopal symptoms resulting in the termination …
